MACHINE FOR CUTTING AND PUNCHING METAL.`

SPECIFICATION forming part of Letters Patent No. 416,860, dated December 10, 1889.

Application led September 13, 1889. Serial No. 323,847. (No model.)

DERs, a citizen of the United States, residing at Lone Elm, in the county of Anderson and y State of Kansas, have invented a new and useful' Machine for Punching and Cutting Metal, of which the following is a speciication.

My invention relates to improvements in machines'for punching and cutting metal; and it consists in certain novel features'hereinafter described and claimed.

In the accompanying drawings, Figure l is a side view showing the punch raised. Fig. 2 is a similar view showing the punch lowered, with a part broken away. Fig. 3 is a horizontal section on the line w a', Fig. l; and Fig. i is a detail vertical section on the line 'y y, Fig. 2.

In carrying out my invention I employ a base A, and on the said base near one edge of the same I erect the standards B B, between which, at and near the upper ends ofthe same, I journal the cog-wheels C C, and the shaft of the lower cog-Wheel is projected through one of the standards B, and is provided with an operating-lever D, as shown. The operatingllever, however, may be readily dispensed with and the machine driven by a steam-engine or other suitable motor. On the upper side of the base I provide the side bars E E,

one of which is provided in its inner side, near end with a blade M, and the die-carrier J is connected to the front end of the said bar by the links N, as clearly shown. The die is secured in the die-carrier by means of a setscrew O, mounted in the side of the die-carrier and adapted to bind against the die after it has been fitted in a recess P in the lower end of the carrier. The die-plate is secured between the front ends of the side bar E and the cross-bars Q, extending between the bars the greater power to the shears, the pivot of,

the pitman is arranged above the shaft or fulcrum of the gear-wheel, and when it is desired to apply the greater power to the punch the pivot is arranged below the said shaft.

From the foregoing description, takenin connection with the accompanying drawings, it will be seen that I have provided a very simple and compactly-arranged machine, in which the several parts are so connected as to be easily operated; and its advantages are thought to be obvious. cut the metal, the metal is inserted between the rear ends of the side bar and the oscillating bar, and the operating-lever then vibrated so as to'cause the oscillating bar to swing in When it is desired to.

the proper direction to bring the rear end of said bar down onto the metal, thereby cutting the same, as will be readily understood upon reference to the drawings. When it is desired to punch metal, the machine is operated so as to bring the front end of the oscillating bar downward. The arrangement of parts is such that a powerfulforce is exerted on the metal with the expenditure of comparatively l little labor. The gear-wheels multiply the power exerted thereon, and this power is transmitted through the pitman U and the le vers T. directly to the oscillating bar. The punch is guided in a true vertical line by the hollow offset I, and the oscillating bar is prevented frorn having any lateral movement by the lugs on the side bars. The levers T, being secu red in grooves in the oscillating bar, will vibrate the Vsaid bar positively and will not produce any lost motion.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The combination ofthe side bars, the oscillating bar pivoted between the same and provided with grooves in its sides, the levers having their lower ends secured in said grooves, the cog-wheels, the pitmau having its rear end pivoted between the ends of the levers and its front end pivoted to one of the cog-Wheels, and means for operating the said Wheels, as set forth.

2. -The combination of the side bars, one of which is provided with aknife at its rear end and the other one having a hollow oset at its front end, the oscillating bar pivoted between the said side bars and having a knife at its rear end, the die-carrier connected to the front end of the oscillating bar and playing in the hollow oifset of the side bar, and

mechanism for operating the oscillating bar,

as set forth.

In testimony that I claim the foregoing as my own I have hereto aixed my signature in presence of two Witnesses.
